Port Forwarding with 2 NICs via Windows 7 firewall

Question

I have a computer with two network cards, each of them connected to a separate network. I would like to forward all requests that arrive via port X from one networks to port Y on a host in the other network.

Is this something I can realize with the Windows 7 firewall and if yes, what would a configuration like this look typicially look like?

Thanks!
